Vickers microhardness studies of Fe-Mn binary alloys
(Elsevier Science Bv, 2004)
The room temperature microhardness of Fe-Mn binary alloys with different compositions was measured using a Vickers microhardness tester in the applied load ranging from 0.245 to 4.9 N. A significant indentation size effect ...
Prism coupling technique investigation of elasto-optical properties of thin polymer films
(Amer Inst Physics, 2004)
The use of thin polymer films in optical planar integrated optical circuits is rapidly increasing. Much interest, therefore, has been devoted to characterizing the optical and mechanical properties of thin polymer films. ...
A phytosociological research on the degraded forest vegetation of dinek mountain (Kırıkkale)
(2004)
IBu çalışmada Dinek Dağı (Kırıkkale) bozuk orman vejetasyonu Braun - Blanquet metodu ile analiz edildi. Yapılan vejetasyon çalışmaları sonucunda iki bitki birliği tanımlandı. Bilim dünyası için yeni olan bu birlikler ve ...
Affinity membrane chromatography: relationship of dye-ligand type to surface polarity and their effect on lysozyme separation and purification
(Elsevier, 2004)
Two different dye-ligands, i.e. Procion Brown MX-5BR (RB-10) and Procion Green H-4G (RG-5) were immobilised onto poly(2-hydroxyethylmethacrylate) (pHEMA) membranes. The polarities of the affinity membranes were determined ...
Crystal and molecular structure of 3-phenyl-4-(p-chlorobenzylamino)-4,5-dihydro-1-H-1,2,4-triazol-5-on
(Wiley-V C H Verlag Gmbh, 2004)
The structure of the title compound, C15H13N4OCl was determined by single crystal X-ray diffraction technique. The structure consists of a p-chlorobenzylamino moiety and triazol and phenyl rings. The title compound ...
Covalent immobilization of invertase on microporous pHEMA-GMA membrane
(Elsevier Sci Ltd, 2004)
Poly (2-hydroxyethyl methacrylate-glycidyl methacrylate) (pHEMA-GMA) membrane was prepared by UV-initiated photopolymerization. Invertase was immobilized by the condensation reaction of the epoxy groups of glycidyl ...
Controlled release of insecticide carbaryl from crosslinked carboxymethylcellulose beads
(Parlar Scientific Publications (P S P), 2004)
Copper-carboxymethylcellulose (CuCMC) beads containing carbaryl were prepared by the ionotropic crosslinking of sodium carboxymethylcellulose (NaCMC) with copper ions. The beads were characterized by carbaryl encapsulation ...
Evaluation of lysozyme adsorptive behaviour of pHEMA-based affinity membranes related to the surface energy and its components to be used in chromatographic fields
(Elsevier, 2004)
We have studied the influence of the surface energy and its components of two different dye-ligand immobilised poly(hydroxyethylmethacrylate) (pHEMA) membranes to the adsorption of a protein "lysozyme" from aqueous solutions. ...
Permeation and separation characteristics of acetic acid/water mixtures through poly(vinyl alcohol-g-itaconic acid) membranes by pervaporation, evapomeation, and temperature-difference evapomeation
(Wiley, 2004)
In this study, itaconic acid (IA) was grafted onto poly(vinyl alcohol) (PVA) with cerium(IV) ammonium nitrate as an initiator at 45degreesC. The grafted PVA was characterized with Fourier transform infrared spectroscopy, ...
E2/M1 multipole mixing ratios of transitions in erbium isotopes
(2004)
Erbium isotopes (Z = 64) lie in the transitional region that occurs at the middle of the range of deformed nuclei. ?-ray E2/M1 mixing ratios for selected transitions in 166-168Er are calculated in the proton-neutron ...
